New research led by scientists from Newcastle University and the University of Nottingham has shown that typical teenage behaviour doesn't just occur in young humans - it happens in dogs too.
The study, headed by Dr Lucy Asher from Newcastle University, is the first to find evidence of adolescent behaviour in dogs.
COVID-19's rapid spread throughout the world has been fueled in part by the virus' ability to be transmitted by people who are not showing symptoms of infection.
Now, a study by researchers at Princeton has found that this silent phase of transmission can be a successful evolutionary strategy for pathogens such as viruses like the one that causes COVID-19. The study was published May 8 in the journal Proceedings of the National Academy of Sciences.
RICHMOND, Va. (May 12, 2020) -- Psychopathy is widely recognized as a risk factor for violent behavior, but many psychopathic individuals refrain from antisocial or criminal acts. Understanding what leads these psychopaths to be "successful" has been a mystery.
A new study conducted by researchers at Virginia Commonwealth University sheds light on the mechanisms underlying the formation of this "successful" phenotype.
New imaging technology allows scientists to see the widespread loss of brain synapses in early stages of Alzheimer's disease, a finding that one day may help aid in drug development, according to a new Yale University study.
COVID-19, the disease caused by coronavirus SARS-Cov-2, has infected over 4 million people in 212 countries, of whom at least 272,000 have died. The ongoing economic and social impact of the pandemic is staggering, but despite a daily flood of news on the disease, few laypeople know that paradoxically, COVID-19 mostly kills through an overreaction of the immune system, whose function is precisely to fight infections.
Blockchain, the technology that underpins digital currency and has acquired a slightly tainted reputation as a useful tool for organised crime, is coming out of the shadows and is set to become a friend to consumers, protecting them from tainted food, fake medicine, fraud and products with illegal or unethical origins, a new study from the University of Bath shows.
To some, farming might seem simple: plant seeds, help them grow, then sell the product. But the reality is much different. Farming requires many complex decisions throughout the year.
One such decision is seeding rate - the number of seeds planted per acre. The best seeding rate for soybean fields is one of the most debated topics for those involved in agriculture.
Researchers at Orygen and La Trobe University in Melbourne, Australia have completed a rapid review of contemporary epidemic and pandemic research to assess the potential impact of COVID-19 on people with psychosis.
A group of tiny RNA that should attack the virus causing COVID-19 when it tries to infect the body are diminished with age and chronic health problems, a decrease that likely helps explain why older individuals and those with preexisting medical conditions are vulnerable populations, investigators report.
What The Study Did: Claims data for nearly 200,000 Medicare patients were used to examine the association between starting pulmonary rehabilitation within 90 days of being hospitalized for chronic obstructive pulmonary disease (COPD) and survival after one year. Pulmonary rehabilitation involves exercise training and self-management education.
Authors: Peter K. Lindenauer, M.D., M.Sc., of the University of Massachusetts Medical School-Baystate, Springfield, Massachusetts, is the corresponding author.
What would you do if the person standing next to you would suddenly scream and run away? Would you be able to carry on calmly with what you're doing, or would you panic? Unless you're James Bond, you're most likely to go for the second option: panic.
But now imagine another scenario: while out on the street, the person walking in front of you suddenly freezes: she stops moving and becomes perfectly still. What would you do?
Neuroscientists at the Ruhr-Universität Bochum (RUB) together with colleagues at the Freiburg University show that this is not strictly the case. Instead, they show that prediction errors can occasionally appear as visual illusion when viewing rapid image sequences. Thus, rather than being explained away prediction errors remain in fact accessible at final processing stages forming perception. Previous theories of predictive coding need therefore to be revised. The study is reported in Plos One on 4. May 2020.
The greenhouse gas methane is a crucial factor of climate change in the Arctic and globally as well. Yet, methane emissions in the far north are difficult to measure across large regions. In the past, researchers usually scaled-up selective point measurements to generate landscape-scale methane flux estimates. Now, a group of researchers from Alaska and Germany is reporting for the first time on remote sensing methods that can observe thousands of lakes and thus allow more precise estimates of methane emissions.
Highly complex organisms can arise from a single cell, which is one of the true miracles of nature. Substances known as morphogens have an important role in this development, namely by signalling to cells where they should go and what they should do. These signal molecules guide biological processes such as the formation of body axes or the wiring of the brain. To investigate such processes in more detail, researchers have to be able to position the signal molecules among living cells in three-dimensional space.
The genetic information within our cells is what makes humans unique. The cell nucleus has a complex structure that harbors this genetic information. The main component of the nucleus is chromatin, an intercalated pool of genes and proteins. Promyelocytic leukemia (PML) bodies are structures found closely associated with chromatin, suggesting that they may be involved with genetic function. However, the exact nature of the relationship between PML bodies and genes is unknown.
